"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nscsi: qla2xxx: Fix queue teardown NULL dma_free and bitmap locking\n\nqla25xx_free_req_que() and qla25xx_free_rsp_que() have two pre-existing\nbugs exposed on the error path of qla25xx_create_{req,rsp}_que():\n\n 1. When dma_alloc_coherent() fails during queue creation, the error\n path calls the free function with req->ring / rsp->ring still NULL\n (from kzalloc). The unconditional dma_free_coherent() with a NULL\n cpu_addr is undefined behavior and can panic.\n\n 2. The free functions clear req_qid_map / rsp_qid_map under vport_lock,\n but the create functions protect the same bitmaps with mq_lock.\n This provides no mutual exclusion. Additionally, the create error\n path clears the bit and releases mq_lock before calling the free\n function, creating a window where another thread can allocate the\n same que_id and have its ha->req_q_map entry clobbered by the\n subsequent lockless NULL assignment in the free function.\n\nFix by:\n\n - Guarding dma_free_coherent() with a NULL check on the ring pointer.\n\n - Using mq_lock (the lock held by all creators) in the free functions\n to atomically NULL the map entry and clear the bitmap bit.\n\n - Removing the now-redundant clear_bit blocks from the create error\n paths since the free functions handle it atomically."
